People for the Ethical Treatment of Animals (PETA) are putting their money where their mouths are with a million dollar contest to see who can grow edible, tasty chicken nugget meat in a lab by 2012. The prospect of lab-grown meat has a lot of promise, but has been around for years without much progress, probably because of a lack of funding. With the prize money on the table, PETA hopes to do for in vitro meat what the Ansari X-Prize did for commercial spaceflight. It's a terrific idea, but one wonders if they've thought this through well — part of the process involves 10 PETA judges tasting experimental, lab-grown chicken nuggets that may not be ready for prime time yet.
